    <dd>This element departs from the standard FRAME structure syntax.
        This <em>IN-LINE</em> framing method (also called &quot;floating
        frames&quot;) is basically a method to embed other HTML documents
        within the framework of a regular HTML document structure with the
        level of placement control allowed by the IMG element. In implementation
        and display it is created and treated much like the OBJECT element is -
        backwards compatibility is achieved by having the contents of the
        element ignored by browsers that understand IFRAME.
        <br><br>
        <b class="alert">Note:</b> HTML 4.0 also allows HTML documents to be
        embedded inline using the <a href="../o/object.htm">OBJECT</a> element.

<ul>
    <li>Use of frames of any type can involve a costly amount of extra
        downloads that a user could quickly tire of.
    <li><a href="../../../testing/html/tags/i/iframe-bp2.htm">[Test]</a>
        There appears to be different default interior padding values controlled
        by the MARGINHEIGHT and MARGINWIDTH attributes. In other words, if only
        one of these attributes is specified, the default for the unspecified
        attribute will be different than the default for the attribute if
        <em>BOTH</em> attributes are specified. [That looks confusing even
        to <em>ME</em> =)] It is possible (though unverified) that in instances
        where only one value is present it is used as the margin value for
        <em>BOTH</em> dimensions.
    <li>The sample stylesheet for HTML 4 says that IFRAME should be considered
        to be a "block" valued 'display' property, but in practice it behaves
        like an "inline" type.
    <li>HTML 4.x+ recommends that authors use the ID attribute instead of the NAME
        attribute wherever possible. ID is the accepted method moving forward and NAME will
        eventually be removed.

<ul>
    <li>Internet Explorer briefly flirted with a syntax for floating frames
        using extensions to the FRAME element. This was changed to the IFRAME element
        in 3.0 Beta 2 to allow for backward compatibility for non-supporting
        browsers. When the old syntax is encountered in versions 3.0 Beta 2 and
        greater, Internet Explorer gives a warning message that the syntax has changed.
    <li><a href="../../../testing/html/tags/i/iframe-bp1.htm">[Test]</a>
        There is an attribute that Microsoft's references list for this
        element called BORDER. It does appear to have some effect, but it appears
        to be to render padding around the frame (which is what the HSPACE and
        VSPACE attributes accomplish) instead of rendering a distinct border
        around the frame.
    <li>Microsoft's references also list FRAMESPACING and NORESIZE as valid
        attributes for this element, but these dynamic attributes do not appear
        to have any effect. They also do not make sense given that an IFRAME
        has a static size.
    <li>Opera 4 ships with IFRAME display capability turned off. To turn
        this on, go to File...Preferences menu, select the Documents category.
        Check the "Enable inline frames" box in the Frames section.
